Title: Large-capacity thyristor switch
Inventor: TANABE SHIGERU
IPC: H03K17/73
Filed: 1979-05-18
Abstract: PURPOSE:To reduce voltage stress of nonlinear resistors by providing voltage divider comprising resistors and capacitors in each of a plurality of thyristors which are connected in series and connecting a nonlinear resistor to each resistor in parallel. CONSTITUTION:At least two thyristor elements 1 are connected in series, and the flow of a load current is blocked and controlled. A voltage divider comprising a series circuit of a resistor 2 and a capacitor 3 which is connected to each thyristor element 1 in parallel is provided. Then, a nonlinear resistor 4 is connected to each resistor 2 in parallel. The riseup voltage in the opposite direction caused by the reverse recovery current which flows at the time of turn-off is absorbed. Therefore, the voltage is applied to the resistor 2 only at the time of turn-on and turn-off of the element 1, and very few amount of said voltage is applied at the steady state. The time length of turn-on period during which the voltage is applied is short. Thus, the voltage stress of the nonlinear resistor 4 can be greatly reduced.

Title: Current supplying circuit for call
Inventor: MASHIBA MINORU
IPC: H04M3/18
Filed: 1985-03-27
Abstract: PURPOSE:To improve the degree of balance of the transmission cable seen from the power supply and thereby to reduce the influence by noises etc. by making the telephone-side windings of a combined transformer a balancing winding and by connecting the intermediate tap of the said windings to the power source for speaking current supplying. CONSTITUTION:The calling current flows from a power source Vcc through a constant current circuit 1 and the transmission cable 3, and is supplied to the speaking circuit of a telephone 4. The current further flows through the transmission cable 3 and a constant voltage circuit 2 and reaches the ground SG. Even when a difference occurs between the impedance of the circuit 1 and that of the circuit 2, the balance between one end T of the cable 3 and the ground SG and that between the other end R and the ground SG is maintained in a high degree because the center point CT of the combined transfirmer T1 that is constituted with an impedance sufficiently lower than both of the said impedances is connected to the power source for speaking current supplying. Therefore, the difference in impedance between the both circuits 1 and 2 can hardly influence the balance.

Title: Image recorder
Inventor: FUJII HARUO
IPC: G03G15/32
Filed: 1982-04-12
Abstract: PURPOSE:To obtain a recorded image of high accuracy free from the unevenness in the image by providing a control means in the position where the aperture centerline thereof maintains roughly the same distance from an electric charged particle generating source. CONSTITUTION:When a high voltage is applied from a high voltage power source 10 to a corona wire 9, ions are formed from the wire 9 and part thereof arrive at the aperture 4 of a control means. When the voltage is applied from a signal source 11 on a signal electrode 1 in this stage, an electric field is generated between the electrodes 1 and 3 and the ions are acted with force in the direction of the electrode 1, by which the ions are passed through the aperture 4 or the passage thereof is blocked by the same. A DC power source 12 applies a DC voltage on the base electrode 3 and a back electrode 5, and the sticking of the ions on the electrode 1 is prevented by the electric field generated by said voltage. The ions are further accelerated so as to stick on the surface of a recording member 6. The apertures 4 in this case are arranged to draw an arc around the wire 9 to make the degrees of the electric charged particles arriving at the member 6 equal. The sharp image having no unevenness is thus obtained.

Title: Remote measuring method and remote bracketing circuit for subscriber's loop
Inventor: FUKUSHIMA SHIGERU
IPC: H04M3/30
Filed: 1991-02-01
Abstract: PURPOSE:To prevent communication from becoming impossible by providing a timer, and restoring automatically a cut-off state set in an opening step after the lapse of time required for a test to be executed in a test step. CONSTITUTION:In order to execute a bracketing test, unipolar high voltage is sent for setting the released state of a line by operating a relay installed in the vicinity of a terminal in an opening step. In the opening step, a contact connected in series to the line is opened by driving the relay. At this point of time, a timer circuit starts. The timer circuit generates a signal after the lapse of the time required for the test to be executed in the test step, and gives the relay an operating current for restoration. Accordingly, since the relay is restored automatically by the timer circuit when it is operated once, even if the relay is operated by an unexpected cause, the communication is never interrupted for many hours.

Title: Wire dot printing head
Inventor: TOUJIYOU YOSHIKAGE
IPC: B41J2/28
Filed: 1986-03-20
Abstract: PURPOSE:To minimize circulation of a magnetic flux between adjoining bypasses and thereby reduce magnetic interference by providing a magnetic channel pattern in which the bypasses of adjoining printing elements are arranged deviated in an armature-moving direction. CONSTITUTION:Bypasses 41a, 41b having a width less than half the pitch of armatures are arranged in a vertically shifted manner between armatures 62 and also in a staggered way so that they may be symmetrical to each other with respect to the armatures. Under this design, the upper bypasses 41a and the lower bypasses 42b are opposed to each other across the armature 62 in their respective groups. Thus a magnetic channel pattern constituting the bypass for each printing element is formed. This enables minimization of a magnetic flux circulation between the bypasses 41a, 41b, and also generates almost no magnetic flux circulation between the bypass (41a or 41b) of a printing element and the armature 62 due to a large gap G between them. Accordingly, if the adjoining printing elements PE-1 and PE-3 are excited simultaneously, the leak amount of each magnetic flux MB-1, MB-3 between the armatures 62-1, 62-3 through the bypass 41a, 41b is insignificant. Therefore, magnetic interference is either reduced or eliminated.
